700079 ÷ 21 
Our goal is to divide 700079 by 21.

Let's proceed to step 1:
7 divided by 21 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 21

Going ahead to step 2:
When dividing 70 by 21, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 63 from 70, we get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 21

Advancing to step 3:
If we divide 70 by 21, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtract 63 from 70 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 21

Moving on to step 4:
When dividing 70 by 21, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 333.0
If we take 63 away from 70, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 21

Advancing to step 5:
21 can be fit into 77 3 times, resulting in a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3333.0
Subtracting 63 from 77 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 21

Going ahead to step 6:
149 divided by 21 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 33337.0
Deduct 147 from 149 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 33337.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 33337.09
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
110 divided by 21 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 33337.095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
21 goes into 50 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 33337.0952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
If we divide 80 by 21, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 33337.09523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 33337.095238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 33337.095238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
200 divided by 21 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 33337.09523809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 33337.09523809 and a remainder of 1.1e-08.
